Have a look at the images of Headroom amp guts.
The Home uses one Talema transformer (toroids available from Digi-Key) and two regulators to make +/- voltages.
The Maxed Out Home uses two Talema transformers and four regulators (for + & -) for seperate left and right channel power.
The Max uses the same configuration but with Avel/Lindberg transformers.
All these power supplies are mounted to the same circuit board as the amplifier parts with no perceivable sonic degradation. It's tider that way.
I would embark on cloning the Maxed Out Home PS for the uber-amp simply because you can get all the parts at Digi-Key.
Barring that (and if you insist on a seperate board for the power supply) you could use a ready-made (or easy-to-assemble) one like Welborne Labs' PS-1.
I've built stand-alone power supplies using the that portion of the circuit of the SDS amplifier project on Headwize with good results.
